HTTP Request with PHP + NuSoap - php

Question

I'm trying to create a http request to our web service, my test XML works when directly inputted into the webservices test input field and I click "Invoke", but when trying to use the same data with PHP + NuSoap, I get a peculiar error which I've been unable to solve, I've tried to google for it but nothing relevant shows up for this case.
Here is the Request:
POST /iInterface_pc2/service.asmx HTTP/1.0
Host: 10.10.86.55
User-Agent: NuSOAP/0.9.6dev (1.137)
Content-Type: text/xml; charset=UTF-8
SOAPAction: "http://www.xxxx.com.cn/TransferMaterialInfo"
Content-Length: 722
<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<TransferMaterialInfo xmlns="http://www.xxxx.com.cn/">
<Materiallist>
<Materialinfo>
<id>123456</id>
<title>Hello word</title>
<datetime>2011-04-23 12:12:12</datetime>
<contributor>Some One</contributor>
<materialurl>www.website.com/path/audio1.mp3</materialurl>
<duration>10000</duration>
<status>0</status>
<remark></remark>
</Materialinfo>
</Materiallist>
</TransferMaterialInfo>
</soap:Body>
</soap:Envelope>
And the Response:
HTTP/1.1 500 Internal Server Error
Cache-Control: private
Content-Type: text/xml; charset=utf-8
Server: Microsoft-IIS/7.5
X-AspNet-Version: 2.0.50727
X-Powered-By: ASP.NET
Date: Thu, 28 Apr 2011 11:04:11 GMT
Connection: close
Content-Length: 428
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<soap:Fault>
<faultcode>soap:Server</faultcode>
<faultstring>Server was unable to process request. ---> Value cannot be null.
Parameter name: s</faultstring>
<detail />
</soap:Fault>
</soap:Body>
</soap:Envelope>
And finally the PHP I use to generate the request
<?php
// include soap file
require_once('lib/nusoap.php');
// set end point
$endpoint = "http://10.10.86.55/iInterface_pc2/service.asmx";
// create client
$client = new nusoap_client($endpoint);
if ( $client->getError() ) {
print "Soap Constructor Error: ";
print_r($client->getError());
}
// Human readable
$request = <<<HEREDOC
<TransferMaterialInfo xmlns="http://www.xxxx.com.cn/">
<Materiallist>
<Materialinfo>
<id>123456</id>
<title>Hello word</title>
<datetime>2011-04-23 12:12:12</datetime>
<contributor>Some One</contributor>
<materialurl>www.website.com/path/audio1.mp3</materialurl>
<duration>10000</duration>
<status>0</status>
<remark></remark>
</Materialinfo>
</Materiallist>
</TransferMaterialInfo>
HEREDOC;
$action = "http://www.xxxx.com.cn/TransferMaterialInfo";
$msg = $client->serializeEnvelope($request, '', array(), 'document', 'encoded', '');
$result = $client->send($msg, $action);
if ( $client->fault ) { //soap_fault
print "Soap Fault :";
print_r($client->fault->faultcode);
print_r($client->fault->faultstring);
}
elseif ( $client->getError() ) {
print "Soap Error :";
print_r($client->getError());
}
else {
print "Result: ";
print_r($result);
}
..print stuff
?>
Any insights and guesses GREATLY appreciated. I've been banging my head against a brick wall for a good while now. :/

Answer 1

I believe the server is seeing the < and > characters and decoding it to >
You may need to urlencode the data before sending

Answer 2

Answer 3

The problem has been solved and was actually caused by faulty ASP code expecting only whitespaces to be html-encoded, resulting in faulty response.
